Mens trousers for extremely swollen leg

[secretgirl]

I'm looking for trousers for a family member who has a medical condition which results in an abnormally swollen leg. He can't get anything to git him and is in the same trousers all the time. He's elderly so doesn't want tracksuit bottoms.
Can anyone recommend there I might get a pair of chinos for him?
Thanks in advance

I think you need a tailor

Just Google disabled clothing mens.
There are numerous sites with adapted clothing.
I know it's doesn't sound PC but it works

I think a tailor/seamstress would be able to adapt them for him - I think you would need to buy two pairs so that one pair can donate fabric to expand the leg as needed. Depending on how swollen it is and where, then poppers or a zip on the outside seam might be required to let him get his leg in without having too much fabric elsewhere, but they could be hidden easily.

Thanks all

Having trouble with link but a company called big and tall menswear. Item B 1073 seems to fit the bill.
